KDM4B and neurodevelopmental disorder: For example, pathological findings are observed in cerebral cortex, amygdala, basal ganglia, and cerebellum and hippocampus in neurodevelopmental disorders.50, 51 Most notably, abnormal neurogenesis in the cerebral cortex is associated with ASD-like behavior.52 Indeed, disorganization of the cerebral cortex is observed in children with ASD.53 JMJD2B, which is strongly expressed in the cerebral cortex at perinatal stages, might also play a role in cortical neurogenesis.
